(Phys.org)—Hydraulically fractured natural gas wells are producing less wastewater per unit of gas recovered than conventional wells would. But the scale of fracking operations in the Marcellus shale region is so vast that ...

Despite increases in efficiency, water demand in the United States is likely to increase substantially in the future if climate continues to warm, new projections indicate. Brown et al. project future water use to 2090 based ...

The past few years have seen powerful droughts across the U.S., with water shortages threatening crop production, shipping traffic, energy production, and groundwater stores. Water scarcity issues are particularly relevant ...

(Phys.org)—Although reports of drought conditions, water wars and restrictions have often painted a bleak picture of the nation's water availability, a new University of Florida survey finds that conditions aren't quite ...

Water is a commodity, and water rights can be freely traded in an open market. Proponents of the free market approach argue that it leads to the most efficient allocation of water resources, as it would for any other commodity. ...

New research suggests that cutting down swaths of forest in snowy regions at least doubles – and potentially quadruples – the number of large floods that occur along the rivers and streams passing through those forests.

Being able to predict the timing and amount of flooding during and following a hurricane or typhoon would improve early warning and mitigation efforts. However, variable typhoon tracks and interaction between typhoons and ...

Previously, gauges used to measure changes in water level in the Amazon were not on the same reference level. This meant water levels could not be directly compared, limiting the use of the gauges in research, especially ...

Variations in the ratios of different isotopes of hydrogen and oxygen in water have long been used to trace water cycle processes, and the isotopic composition of water vapor in the atmosphere is known to change with weather ...
